Question

Length of a rectangle exceeds its breadth by 6 meter .If its perimeter is 64 metre then find its length and breadth

Answer 1

length+6=breadth
Perimeter=2+(l+b)
64=2×[(l×6)+b]
64/2=l+6+b
32=6+2l
32-6=2l
26=2l
26/2=l
13=l

So length+6=13+6
=19
breadth=13

VERIFY
length=19
breadth=13
Perimeter=2×(l+b)
64 =2×(19+13)
64 =2×32
64 =64
LHS =RHS


HOPE IT'S HELPFUL♥♥♥

Answer 2

length = x+6
breadth = X
perimeter = 64m = 2(l+b)
= 2(x+x+6)= 64
= 2x +6 = 32
= 2x = 32-6
= 2x = 26
= X = 13 = breath
length = 13+6 =19
